+* Juniper I2C Mux on I2CS
+
+	I2C mux driver for switching the RE access to the FPC i2c bus.
+	Compatible with the FPC variant of the I2CS.
+
+Required properties:
+
+  - compatible: "jnx,i2cs-mux-i2cs".
+
+The following required properties are defined externally:
+
+  - Standard I2C mux properties. See i2c-mux.txt in this directory.
+  - I2C child bus nodes. See i2c-mux.txt in this directory.
+
+Example:
+
+fpc0_mux {
+	compatible = "jnx,i2c-mux-i2cs";
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	fpc0i2c0: i2c@0 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <0>;
+	};
+};
